Investigation of the use of navigation tools in web-based learning: A data mining approach

Web-based learning is widespread in educational settings. The popularity of Web-based learning is in great measure because of its flexibility. Multiple navigation tools provided some of this flexibility. Different navigation tools offer different functions. Therefore, it is important to understand how the navigation tools are used by learners with different backgrounds, knowledge, and skills. This article presents two empirical studies in which data-mining approaches were used to analyze learners' navigation behavior. The results indicate that prior knowledge and subject content are two potential factors influencing the use of navigation tools. In addition, the lack of appropriate use of navigation tools may adversely influence learning performance. The results have been integrated into a model that can help designers develop Web-based learning programs and other Web-based applications that can be tailored to learners' needs

Copyright @ 2013 Elsevier B.V.Numerous research studies have explored the effect of hypermedia on learners' performance using Web Based Instruction (WBI). A learner's performance is determined by their varying skills and abilities as well as various differences such as gender, cognitive style and prior knowledge. In this paper, we investigate how differences between individuals influenced learner's performance using a hypermedia system to accommodate an individual's preferences. The effect of learning performance is investigated to explore relationships between measurement attributes including gain scores (post-test minus pre-test), number of pages visited in a WBI program, and time spent on such pages. A data mining approach was used to analyze the results by comparing two clustering algorithms (K-Means and Hierarchical) with two different numbers of clusters. Individual differences had a significant impact on learner behavior in our WBI program. Additionally, we found that the relationship between attributes that measure performance played an influential role in exploring performance level; the relationship between such attributes induced rules in measuring level of a learners' performance

Let's not forget those who forget! Participatory design in the context of dementia built environment : Evangelia Chrysikou

Dementia is a major cause of disability and dependency among older people worldwide. Eco-bio-psychosocially supportive design can significantly reduce agitation and depression while improving mobility and daily activities. For this we need to include dementia patients as experts while understanding the neurological changes and functional impairments associated with the progression of the disease over time. How can we support dementia patients to participate? What tools/processes can we use to involve them in the design process? The aim of this project was to map and evaluate co-design methods for dementia and neurodiversity, in order to create an eco-bio-psychosocially supportive environment. Mixed methods were used comprising a systematic literature review on co-design techniques for spaces for dementia, three workshops: a 3-day one with seven early career researchers translating patient involving methodologies to the dementia context, a round table Patient and Public Involvement and Engagement with six service providers and stakeholders cross three countries and a cross-sectoral international day conference with four academics, four early career researchers and eight stakeholders and a series of co-design workshops for dementia and neurodiversity, which were then classified according to applicability so as to generate co-production methods for living environments for dementia. This transdisciplinary project highlighted the challenges of participatory design in the context of dementia built environment. The importance of the topic was highlighted by clinicians and staff but there are still significant limitations in terms of research and methodologies. The workshops outcome was an inclusive code of conduct for participatory design and research for dementia patients, which will help to improve home and care environments for people with dementia. The framework involved aspects such as time, space, equipment in relation to people involved (carers, patients, proxies)

Web-based interaction: A review of three important human factors

With the rapid development of information technology, the World Wide Web has been widely used in various applications, such as search engines, online learning and electronic commerce. These applications are used by a diverse population of users with heterogeneous backgrounds, in terms of their knowledge, skills, and needs. Therefore, human factors are key issues for the development of Web-based applications, leading research into human factors to grow significantly in the past decade. This paper identifies and reviews three important human factors that have been examined in existing empirical studies, including gender differences, prior knowledge, and cognitive styles. The main results from the analysis include that: (a) females have more disorientation problems than males; (b) flexible paths are more beneficial to experts while structured content is more useful to novices; and (c) Field Dependent and Field Independent users prefer to employ different search strategies. In addition to reviewing the existing empirical studies, this paper also highlights areas of future research
